Using the same design technology as the industry standard Reflexion Filter PRO, the sE Electronics RF-X treatment filter was conceived to answer the needs of the discerning recording artist working on a budget. With a lightweight vented body and an efficient, redesigned clamp assembly, the RF-X provides stellar performance. New materials have been developed to make the RF-X lighter than its predecessors while maintaining its durability. It features a four-layer acoustic filter design comprised of the outer vented composite panel, a wool fabric layer, an air gap layer and an inner acoustic foam layer. This multi-layer design differentiates the RF-X from its competitors by filtering frequencies evenly across the whole spectrum, helping to ensuring that recordings exhibit almost zero sound coloration when using the filter.
